T o all whom t may concern.'

'Be it known that I, VILLTAM H. ArrL'nnY, a subject of the King of Great Britain. residing at ll'indsor, in the` county of Essex, Province of Ontario, Canada, have invented certain new and useful Improvements in Radiator Ventilatore and Caps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a radiator ven--v furnish a radiator with .a novel air intake member which will produce an inrush of cold air into the upper portion of the radiator during the operation of an automobile, truck and motor driven vehicle or air craft, to lower the temperature of the water therein and thus increase the efiiciencypf the water as a cooling agent for the engine or power plant of the automobile, particularly in the summer time. It is in this connection that the device is provided with a cap or disk that may be easily and quickly installed to close the filling opening of the radiator during the winter time, and in either instance the device does not interfere with the filling of the radiator in the usual manner, as it is only necessary to remove the ventilator or cap.

My invention further aims to provide a device of the above class which may be more or less ornamental, and provision is made to prevent the splashing of the water or cooling agent from the radiator and at the same time deflect air therein.

My invention further aims lto provide a simple, durable and inexpensive device that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is a perspective view of a portion of the radiator provided with a ventilating device in accordance with my invention;

Fig. 2 is a vertical sectional view of the same; and

Fig. 3 is a similar view showing a cap or disk installed, particularly during the winter time.

In the drawing, the reference numeral 1 denotes a portion of a conventional form of radiator or cooling apparatus forming part of a well known automobile and the cooling principle involved in connection with an engine or motor is commonly known as the f thermo-Siphon system, wherein the hot water seeks a higher level in t-lie radiator or apparatus thairthe cold water, and when the water reaches a predetermined temperature circulation commences through the ra-l diator or cooling apparatus. The top vof the radiator has an opening 2 surrounded by a filling connection 3 which is somewhat frusto-conical shape and has its upper end terminating in an interiorly screwthreaded socket 4, which ordinarily receives a cap,

plug or other closure member.

y device comprises a tube 5 having the lower end thereofv enlarged and exteriorly screwthreaded, as at 6, so that it may be screwed into the socket'l and an annular' flange 7 of said tube limits the screwing` movement of the lower end of the tube rela#A tive to the socket 4, )roviding a small space' S so that a cap or disk 9 may-be seatedV in the socket l and retained therein by the tube 5 to close the connection 3, particularly in the winter time. The cap oi' disk 9 may be made of metal or any suitable material and provides a closure for the filling connection 3 that may be removed byunscrewing the tube 5.

Tlie'upper end of the tube 5 is somewhat funnel shaped by being formed with a substantially semi-cylindrical air intake head 10 having a front open side 11 which faces forward and is adapted to receive air, pai'- ticulai'ly when an automobile is in motion. The air entering the head l0 impinges against the rounded walls of said head and cold air strikes the water or cooling agent in the radiator and reduces the temperature of the same.

To facilitate the deflection of air by the head 10, the open side 11 of said head is provided with a plurality of transverse equally spaced deflectors 12, said defiectors being disposed in parallelism and each at such an angle that air is defiected downwardly into the tube 5. The outer edges of the def'lectors 12 form bars transversely of the front open side of the head 10 and prevent large bodies of solid matter being placed in said head. Any rain that may enter the spaces between the deflectors is cariied downwardly through the tube without contacting with the concave. walls of the head 10, and with the Ventilating device made of aluminum or a metal treated so as not to corrode there is no danger of the general appearance of the Ventilating device detracting from the appearance of the radiator or accessories of the automobile. It is in this connection that the device may be finished to conform to metallic fittings of the automobile, and the shape of the device permits of its being easily manipulated when it is desired to detach the device to ll the radiator.

A screen 14, as a piece of wire gauze, may be placed in the radiator filling connection 3 and held in place by the tube 5, said screen arresting dust and other foreign matter and also serving as an anti-splash member for the contents of the radiator.

I attach considerable importance to the somewhat funnelshape of the device as suff ficient air will begathered in at the open side orend thereof to insurea cooling effect on lthe Water or cooling agent Within the radiator. It is furthermore possible to set the Ventilating device so as to face the Wind, when an automobile is inactive, and thus permit of a draft of air cooling the contents of the radiator, particularly when the engine of the automobile is idling. The de- I vice may also be connected to the ivater jacket of an exposed engine or to any body to which air may be admitted for cooling purposes.

)ne embodiment of my invention has been illustrated, but itI is to be understood that the structural elements are susceptible to such changes as fall within the scope of the ap )ended claim.

The combination with a filling connection of a radiator, the iilling connection having an annular seat, of a funnel shaped air intake device having its lower end connected to the filling connection of said radiator, and a detachable ca on the seat of the filling connectionof said radiate; and retained thereon by the lower endof'said device.

In testimony whereof I aflix my signature in the presence of tivo Witnesses.,

WILLIAM H. APPLEBY.
